old grease jar

[Treeintn]

It appears to be an old grease jar and spoon rest combo.  Its a pig, the top says Lard Head and in the center it has the word spoon. This item is in very good condition.  It has Kalen of California on the bottom. It measures in length from the snout to the back 7" approx 4 1/2" tall and the bottom is approx 3" deep. It also has a pouring spout.

It appears to have a copyrited date, it has '52, perhaps 1952? It is also numberd. The number 16 is written on the bottom and also under the lid.  

Can anyone help me out with this one?
